Also known as ethyl alcohol or alcohol, (C2H5OH)
is an oxygenated hydrocarbon that can be burned as a fuel, or blended into
gasoline. Thought of as an alternative fuel and clean fuel, ethanol is a
renewable energy source that is made from corn or other grains. If blended into
gasoline, ethanol helps with the combustion process and therefore less unburned
hydrocarbons form. Ethanol blended fuels competed with methyltertbutylether (MTBE),
but because of the cost and the fact MTBE can be shipped through exisisting
pipelines, MTBE was chosen. MTBE is now being banned because of its ability to
travel in ground water and the bad taste it imparts to drinking water, because
of this ethanol is once again being put back into the gas.
